Abstract
An exhaust coupling for a pump is disclosed. The exhaust coupling for a pump, comprises: an inlet chamber defining a coupling inlet for receiving a fluid from said pump; an outlet chamber defining a coupling outlet for outputting said fluid from said exhaust coupling; and a non-linear inter-chamber conduit fluidly coupling said inlet chamber with said outlet chamber for conveying said fluid from said inlet chamber to said outlet chamber. In this way, noise from the pump is abated since it is initially dampened when received in the inlet chamber, then dampened further by the non-linear inter-chamber conduit, before being dampened yet further within the outlet chamber prior to being emitted through the coupling outlet. The presence of the non-linear inter-chamber conduit ensures that there is no direct, linear path along which the noise can travel from the coupling inlet to the coupling outlet.
